Performs evidence-driven code review for pull requests, legacy modules, and quality-critical changes. Use when reviewing complex or multi-file changes, test automation suites, architectural refactors, or hot paths that need analysis of correctness, maintainability, security, performance, test quality, and operability…
Performs a quick, lightweight review of a small diff or single file, giving concise feedback on correctness, readability, tests, and obvious risks. Use when the user asks for a fast sanity-check review of a small change. For test-automation suites, architectural refactors, security-sensitive paths, or multi-file…
Shapes QA output for the person who has to act on it: result and blocker in the first two lines, one decision per report, findings ordered by what they cost, the long artifact in a file and the decisions in the message, and magnitude stated in units the reader can count. Use when a report is accurate but nobody acts…
Creates GitHub Copilot custom agents (.agent.md) for VS Code. Use when defining a specialized agent role, selecting a minimal toolset, referencing supporting skills, or shipping install-ready agent examples with clear boundaries and collaboration rules.
Creates GitHub Copilot hooks for VS Code using hooks.json, supporting scripts, and companion docs. Use when automating deterministic checks, pre/post tool policies, or reusable hook packs that need safe defaults, observability, and clear installation guidance.
Creates GitHub Copilot instruction files for VS Code, including repository guidance and scoped .instructions.md rules. Use when encoding project conventions, choosing applyTo patterns, or shipping install-ready instruction examples with rationale and guardrails.
Creates agent orchestration packs: cooperating .agent.md files with an orchestrator, subagents, matched handoffs, minimal tool grants, and a shared handoff packet contract. Use when one agent role is too broad for a job, when a workflow needs explore, plan, implement, review, and verify as separate roles, or when a…
Packages repository skills as installable Copilot plugins: marketplace registration, plugin.json manifests, generated skill copies, and the sync check CI enforces. Use when bundling one or more skills for installation, when adding a plugin to the marketplace, or when npm run lint reports that a plugin copy has drifted…
Creates GitHub Copilot prompt files (.prompt.md) for VS Code. Use when building reusable workflow starters that route work to the right agent, collect the right inputs, and ship with install-ready templates, examples, and validation guidance.
Creates GitHub Copilot skills with reusable workflows, companion resources, and validation gates. Use when packaging repeatable expertise into a SKILL.md folder, deciding what belongs in the skill body versus resources, or producing install-ready skill examples for a team or collection.
Derives a project-specific quality contract from three axes - risk profile, team maturity, and product surface - labelling each testing practice MUST, SHOULD, or COULD, then produces a PRESENT/PARTIAL/MISSING/WAIVED gap matrix with an ordered remediation plan. Use when a project has no agreed testing strategy, when a…
Designs risk-based functional test plans, manual test cases, regression slices, and automation handoff packs from requirements, URLs, or exploratory notes. Use when preparing manual QA coverage before automation, turning feature descriptions into scenario catalogs, or converting exploratory findings into structured…
Designs realistic, boundary-heavy, and role-aware test data packs for manual and automated testing. Use when a feature needs deliberate inputs and fixtures before execution, when edge-case values keep being improvised, or when automation needs stable example data with setup notes.
Writes the documentation a test suite needs to be usable by someone who did not build it: run instructions, environment setup, tag glossary, ownership, fixture and data notes, and architecture decision records. Use when onboarding someone into a suite, when "how do I run these" keeps being asked, when a test…
Generates the CI workflow that enforces a quality contract: layered jobs from fast local hooks to release gates, per-practice steps for JS/TS toolchains, diff-scoped checks, sticky PR reporting, required-check wiring, and a severity policy deciding what fails the build. Use when quality practices are agreed but not…
Turns "we will skip this check for now" into a dated, attributed, expiring waiver with a stated reason and owner, inventories the silent skips already hiding in a repo - skipped tests, disabled lint rules, ts-expect-error, continue-on-error, lowered thresholds, coverage ignores - and reports expired waivers as…
Keeps test data legally and operationally safe: classifies personal data, replaces production copies with synthetic or anonymized fixtures, manages secrets in local runs and CI, strips personal data from traces and HAR files, and sets retention rules. Use when tests run against a production data copy, when fixtures…
Migrates Cypress, Selenium, WebdriverIO, or Protractor suites to Playwright in staged slices, each with a parity gate before the old test is deleted. Use when porting a legacy browser suite, when deciding which tests are not worth porting, when a half-finished migration has stalled with two suites running in parallel…
Decides what to fake and stubs it correctly: network interception with Playwright route or HAR replay, MSW handlers, fake clocks, and fixed timezones. Use when a test depends on a third party, when a date-sensitive test breaks overnight, when a suite is slow because it calls real services, or when a mocked test stays…
Runs session-based exploratory testing: writes charters, timeboxes sessions, applies coverage heuristics and tours, captures notes as evidence, debriefs, and converts findings into bug reports and automation candidates. Use when a feature needs testing before requirements settle, when scripted cases keep passing while…
Produces production-ready Product Requirements Documents (PRDs) for software systems and AI-powered features, with clear problem framing, measurable outcomes, scoped functionality, testable requirements, and explicit risks. Use when the user wants to write a PRD, define requirements, plan a feature, or turn a vague…
Requires an externalised rationale for high-risk changes - new public exports, new endpoints, auth edits, migrations, removed guards - recorded as an Intent commit trailer, an ADR reference, or a module intent register, and reports high-risk changes that carry none. Use when agent-generated or AI-assisted changes ship…
Transforms rough tester notes, screenshots, console output, or observed behavior into reproducible defect reports with severity, evidence, and follow-up guidance. Use when logging bugs, triaging intermittent issues, or rewriting vague defect notes into developer-ready reports.
Maps requirements (PRD, user stories, acceptance criteria) to planned test coverage via a Requirements Traceability Matrix, exposing coverage gaps, risks, test levels, prioritization, and automation candidates. Use when designing coverage from a specification, checking coverage completeness for a PRD or user story…
